Description

Anti-theft tag

The present invention relates to for antitheft or anti-theft and be pasted on anti-theft tag on the commodity, particularly the anti-theft tag of in use battery being checked.

The general practice is by double sticky tape anti-theft tag to be pasted on the extensive stocks such as the blattnerphone showed in the shop or camera.When the thief stripped down this anti-theft tag, cut off on the cable of connection and takes out of commodity outside the shop, this anti-theft tag can give the alarm, thereby notifies the salesman.

Less framework internal admission at above-mentioned anti-theft tag has alarm devices such as power-supply battery, hummer, be formed with the circuit main board of the circuit for alarming that is connected with alarm device with this power supply, be used to detect the parts such as detector switch of theft situation.The cable of ring-type also further extends to the framework outside from circuit main board, thereby this cable can be connected with bar of the displaying canopy of commodity etc.

Fig. 4 represents the existing example of above-mentioned anti-theft tag.In the figure, framework 1 is formed by plastic or other material, within it portion be provided with battery as power supply 2, the circuit for alarming 3 that constitutes by the P.e.c. mainboard, as the hummer of alarm device 4, detector switch, the power switch 6 of circuit for alarming 3, action component 7 of power switch 6 etc. are installed in addition.Cable 8 extends to the outside of framework 1 from circuit for alarming 3, and double sticky tape 9 is pasted on the stickup face 1a of framework 1.

Detector switch 5 is such push switch, this push switch extends on stickup face according to vertical direction along the hole 1b on the stickup face 1a that is opened in framework 1, is under the pressed status at this switch, and alarm device 4 is in dissengaged positions, be under the outstanding state at switch, alarm device 4 is connected.But, when temporary transient connection,, do not cut off if power switch 6 itself keeps this state, then alarm device 4 does not stop action.

Fig. 5 represents the user mode of above-mentioned anti-theft tag.

At first, make preceding end cable 8a in the cable 8 around the making a circle in week of the fixed bar 10 in the upright display canopy of being located at commodity etc., thereby this preceding end cable 8a is connected fixed bar 10 by framework 1 with anti-theft tag.Because the two ends of fixed bar 10 are fixed on canopy or the wall etc., like this can not cable 8 be moved and its opposed end is pulled up along fixed bar 10.Then, power switch 6 is connected, by double sticky tape 9 this anti-theft tag is pasted on the stationary plane 11a of commodity 11 afterwards by push action parts 7.Thus, detector switch 5 is pushed, and alarm device is in standby condition.

Fig. 6 is the circuit diagram of circuit for alarming 3.End as the hummer of alarm device 4 is connected with positive pole one side of power supply 2 by power switch 6, and its other end is connected with collector among the transistor Q3.Emitter among this transistor Q3 is connected with the negative pole of power supply 2, and the base stage among the transistor Q3 is connected with collector among the transistor Q2 by resistor R 3.Base stage among the transistor Q2 is connected with collector among the transistor Q1 by resistor R 4, and the emitter among the transistor Q2 is connected with positive pole one side of power supply 2.Resistor R 1, detector switch 5 and cable 8 are connected mutually, and are connected with the two poles of the earth of power supply 2.Base stage among the transistor Q2 is connected with collector among the transistor Q1 by resistor R 2, is connected between resistor R 1 and the detector switch 5 by diode connected in parallel D simultaneously.Collector in the transistor 2 is connected by resistor R 4 with base stage among the transistor Q1.Emitter among the transistor Q1 is connected with the negative pole of power supply 2.

In said structure, under anti-theft tag was pasted on state on the commodity, detector switch 5 was connected, and power switch 6 is connected.At this moment, electric current is according to the loop flow of power supply 2 → power switch 6 → resistor R 1 → detector switch 5 → cable 8 → power supply 2.Transistor Q1, Q2, Q3 is in cut-off state, and alarm device 4 is in dissengaged positions, and electric current does not flow, thereby does not give the alarm.

When the thief when commodity 11 are peeled off down anti-theft tag, detector switch is 5 outstanding, and cut off.So electric current is from resistor R 1, flow to its emitter, transistor Q1 conducting through diode D, base stage from transistor Q1, the base stage among the transistor Q2 is by resistor R 4 ground connection, transistor Q2 conducting.When transistor Q2 conducting, between the base stage～emitter of electric current from resistor R 3 inflow transistor Q3, transistor Q3 conducting, thus alarm device 4 sends the action of the sound.When transistor Q3 conducting, even be at detector switch 5 under the state of connection, Q1 keeps conducting state, and alarm device 4 does not stop to send the action of the sound.In order to make alarm device 4 stop action, power switch 6 must be cut off.

But, when above-mentioned existing anti-theft tag uses in the mode on the commodity of being pasted on, can peel off inferior situation, alarm device is failure to actuate really afterwards, and this equals not use.Even battery under obsolete state, still can discharge naturally, thereby can not make the alarm device action in the long preservation process.Thus, must check battery this moment.

If the time that is pasted on the commodity is shorter, can before pasting, check, but also want battery, when the stickup time is longer, because the discharge process in this process, dead battery, at the crucial moment of taking place to steal, alarm device does not move.

Owing to, can whether move to alarm device 4 and check for power supply 2 is checked, anti-theft tag can be peeled off down from commodity like this, detector switch 5 is cut off.Or also can cut off cable 8.

But, when for check battery, temporarily when commodity are peeled off down anti-theft tag, spend certain hour this anti-theft tag is pasted on the commodity once more.When cutting off cable 8, can not simply cable 8 be connected, thereby can not reuse this cable 8.Even in addition under the situation about before pasting, checking, when temporary transient detector switch 5 cuts off, even if this switch returns to on-state, alarm device still sends the sound continuously, if do not cut off the electricity supply switch 6, then this alarm device does not stop action, and the operation of Jian Chaing is comparatively complicated thus.

The present invention proposes at above-mentioned situation, the object of the present invention is to provide a kind of anti-theft tag, and this anti-theft tag can be checked battery simply.In addition, another object of the present invention is to provide a kind of anti-theft tag, this anti-theft tag can be checked battery under the state that is pasted on commodity etc.
